If you are on Windows, I use a handy program called xplorer2 which has a command "Browse Flat" which will flatten the Calibre folder structure (in memory) and let you browse it that way.

Hi, I have just been trying the save to disk option; trying to save many books that I already converted earlier this evening from .lrf to .epub.

However, when I saved them to 1 file location, for some reason only some of the selected files went to designated location, and only the author.extension. i.e. somehow the title and other metadata was lost?

Any suggestions, as if I can utilise the save to disk function from the separate location, it will save much cutting and pasting from the sub files that were created upon conversion in the calibre library.
